CARPET 0R RUG FASTENER.

Application filed- May 12, 1922. Serial No. 560,329. r

T 0 all ham it may concern:

Be it known that 1, WILLIAM. finoonrn, a citizen of the United States of America, of Oswego, in the county of Oswego, in the State of New York, have invented new and useful Improvements in Carpet or Rug Fasteners, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to a carpet or rug fastener involving the use of a lever operated clasp mounted on a suitable sheet metal support which is detachably inter-locked with the socketed head of a screw adapted to befastened to the floor or stair tread with its head substantially flushed with the surface thereof.

The main object isto providea device of this character by which the carpet or rug may, be easily and quickly attached to and detached'from the floor or stair tread stud and at the same time to be able" to securely hold the carpet injplace when in operative position.

Other objects and uses relating to specific parts of the device will be brought out in the following description.

In the drawings:

Figures 1 and 2 are, respectively, a front elevation partly in section and a side elevation of a stair carpet fastener embodying the features of my invention, portions of the tread and riser of the stair being shown in section.

Figure 3 is a top plan of a modified form of my invention and is used for securing rugs or carpets to floors.

Figure 4 is a longitudinal sectional view taken on line 44, Figure 3. V

The stair carpet fastener shown in Figures 1 and 2 consists of an angle plate 1 of sheet metal having a horizontal flange -2 and a vertical flange 3 adapted to fit in the corner at the junction of the tread -A with the riser B of the stair case.

The upright flange 3- of the plate 1- is provided with an extension 4- integrally united to one end thereof and returned across the outer face toward the opposite end, the major portion of its length being of slightly less vertical height although the upper edges of the flange --3- and extension -4: are disposed in substantially the same horizontal planes,

The extension 4: is provided with 'a spring tongue -5 cut from the intermedi ate portlon-thereof along spaced lines -6 but integrally united thereto at '7- near the return bend of the extension 4, the remaining portions of the tongue being free from attachment to the extension and extending the major portion of the length thereof substantially midway between the lower'and upper edges so as to be free to move toward and from the upright flange 3 for impingingand releasing the adj acent portions of the stair carpet as -C- between the free end of the tongue and upi right flange.

A cam lever 8- isprovided near one end with opposite pintles -9 which are normally seated in bearings -10- in the adjacent walls of the opening as 11 formed by the cutting of the tongue 5 therefrom, said lever being provided with i an inwardly projecting offset or cam portion ,'12- at substantially'right angles to the main body of the lever'and a short distance inwardly to the axis of the. pintles 9 for engaging the outer face of the tongue and forcing the latter into gripping engagement with the intervening portion of the carpet -C-x: when the leveris rocked fiatwise against the outer end of the tongue.

That is, the tongue and handle portion of the lever 8 are of approximately the same width to allow the handle portion of the lever to move into and out of the opening as 11 through an arc of approxi-v mately 90 degrees or from its extreme looking position to its extreme open position.

The horizontal flange -2 is provided with a reinforcing member 13 also of sheet meta-l spot welded or otherwise firmly secured thereto for receiving and supporting a button 14 which is also secured by spot welding or otherwise to the under side of the reinforcing member 13.

A screw or equivalent fastening member -15 is fastened to the stair tread A- with its upper end or head substantially flushed with the surface thereof, said head being provided with a socket --16,- the walls of which are slitted at intervals at -17- from the top downwardly to form spring jaws for the reception and frictional retention of the button -l4, said screw being also provided with a transverse slot 18 for the reception of the screw driver or equivalent implement by which the screw may be forced inwardly into the wooden tread.

Operation.

The screws 15 are first secured in place to the stair tread or floor with the upper ends of their sockets 16 substantially flushed with the surface thereof, it being understood that these screws will be placed along the edges of the rug a short distance inwardly therefrom so that when'the rug or carpet is in place, it will cover and conceal the buttons and overlying portions of the back plates as -3 or 3 of the fasteners.

When the levers 8 are thrown to their open positions as shown by dotted lines in Figures 2 and 4, the tongues 5 will of course, be opened under their own tension after which, the clips may be fastened to the screws by simply pressing the buttons -14tin the sockets 16, thereby bringing the flanges 2- or 3 close to the floor or stair tread surface.

When the clips are placed in proper position with their open sides facing the edges of the carpet or rug, those edges may be drawn into the clips between the flanges 3 or 3' and return extensions -4 and also between said flanges and the free ends of the tongues 5 whereupon the levers -8- may be closed down flatwise against the outer faces of the extensions 4 to cause the cams -12 to tighten the tongues against the adjacent portions of the carpet or rugs to hold the latter in place, said carpets or rugs being released in reverse operation .of the levers.

V/hat I claim is:

1. A carpet fastener comprising a floor member having a socketed head, a U-shaped clip having one side provided with a button adapted to be inserted in said socketed head and its other side provided with a tongue, anda cam lever on the last named side for moving tlic'tongue toward the opposite side.

2. A. carpet fastener comprising a floor member having a socketed head, a U-shaped clip adapted to receive the edge of the carpet between its opposite sides and having one side provided with a button for frictional engagement in the socketed head, a spring tongue having one end attached to the clip near the junction of said sides and its other end free to move in the intervening space, and a cam lever mounted on the clip for operating said tongue to grip the adjacent portion of a rug or carpet between opposite sides of the clip.

In witness whereof I have hereunto my hand this 27 day of April 1922.
